Carlsen, Caruana & Aronian decided NOT to have playoff and share chess title

The 2018 Sinquefield Cup chess tournament took place from August 18-27, 2018

The craziness of playoff rule for Carlsen, Caruana and Aronian!

It is kind of confusing but here is my understanding. If 2 players tie, they would have a playoff. If there are more than 2, then the top 2 on tiebreaks would head to the playoff. But it seems that no one thought of the idea of 3 or more players having identical tiebreak criteria.

1) Carlsen, Caruana and Aronian drew each other.

2) All three have an identical amount of wins (2 each).

3) All three have the same identical amount of wins with black (0) as they all won with white.

4) The final option is a drawing of lot which means that one player would be eliminated without playing a single move.

The players did not like that idea. So a proposal was made to amend the rules to have a 3 way playoff but Caruana refused because he already has a playoff against So scheduled. It would be unfair for him to have to have 2 playoffs.

Without any other fair and logical option, the 3 players decided to share the title. This is my understanding.

What do you think? What should the rules be?

Below are the playoff rules in case of ties. But the players had the last words and decided to share the chess title, as announced by the organizers.

  1. Preamble
